The recently redesigned Environment Museum in the city's botanical gardens opens once more to the public in perfect time for the Rio+20 event, boasting a state-of-the-art exhibition intended to make explicit, were it not already, mankind's links to his environment. Divided into four parts, beginning with 'Equilibrium', where visitors must maintain their balance to keep the images of nature projected on the walls in harmony, interactivity is the key to keeping younger interests piqued. That includes projections onto mannequins that show the impact of natural disasters on populations and a series of lazers hitting a map of the Earth to highlight the plights of urban populations, refugees and waste control. The fourth room hosts video installations on the themes of Body, Forest and Water, curated by Marcello Dantas, a leading figure in the convergence of art and technology in Brazil.
